Abstract

The invention discloses an integrated rotor shaft for a pneumatic submerged pump, which comprises a first bearing mounting section, a blade mounting section, a second bearing mounting section, a transition section and an impeller mounting section which are arranged sequentially, wherein the diameter of the first bearing mounting section is 3.5-5cm; the diameter of the blade mounting section is 10-12cm; the diameter of the second bearing mounting section is 3.5-5cm; the diameter of the transition section is 3-4cm; the diameter of the impeller mounting section is 1.5-3cm; and the rotor shaft is made of stainless steel. With the adoption of the mode, the integrated rotor shaft is simple and reasonable in structure, and high in strength, and can meet a requirement of the integrated pneumatic submerged pump.

Description

technical field [0001] The invention relates to the technical field of submersible pumps, in particular to an integrated rotor shaft for a pneumatic submersible pump. Background technique [0002] Submersible pump is an important equipment for deep well water extraction. When in use, the whole unit submerges into the water to extract groundwater to the surface. It is widely used in domestic water, mine rescue, industrial cooling, farmland irrigation, seawater lifting, ship loading and other fields. Many of the existing pneumatic submersible pumps have an integral structure of the pump body and the air motor, which requires an integrated rotor shaft. The existing rotor shaft structure is not reasonable enough and the strength is not high. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide an integrated rotor shaft for a pneumatic submersible pump, which has a simple and reasonable structure and high strength. [00...
